PREPARATION

In a small pot, combine garlic and oil, heat over low flame and gently cook until garlic is light golden in color and very fragrant, about 10-15 minutes. Remove garlic cloves and reserve.

Pile cauliflower on baking sheet and dress with lemon juice, about 3-4 tablespoons of the garlic-infused oil, thyme, salt and pepper. Toss to combine and spread florets out in a single layer. Roast to brown at edges and tender, 20-25 minutes. Cover with Parmigiano-Reggiano and roast 5 minutes more. Turn oven off.

Meanwhile, boil parsnips in salted water to tender, 10-15 minutes. Pure in a food processor with the garlic cloves.

Bring a large pot of water to a boil for the pasta.

In a saucepot, combine remaining garlic oil and butter over medium heat. When butter foams, whisk in flour, cook 1 minute; add stock and milk, and thicken. Season with salt, pepper and nutmeg; combine sauce with parsnip pure and melt in cheese.

Cook pasta to al dente, drain pasta and toss with sauce. Arrange in a serving dish topped with crispy cauliflower florets on top.
